SampleFilter.js uniform resolution should be type vec2, not vec3

[VictoryRice]

The SampleFilter.js included in the filters directory says in the comments,

By default the following uniforms are already created and available:
...
uniform vec3 resolution - The dimensions of the filter. Can be set via setSize(width, height)

Actually I've found it must be declared as uniform vec2 or else errors ensue. You can see in the Fire.js filter example that it's a vec2.

Very true - fixed :)
